FEEDING MECHANISM FOR ACETYLENE-GENERATORS.

Specification of Letters Patent.

Patented Oct. 30, 1906.

Application filed May 4,1906. Serial No. 258.745.

To all whom it may concern:

Be it known that I, LOUIS E. SHAW, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Feedin l\rlec.hanis m for Acetylene Generators, which the following is a specification accompanied bydrawings.

This invention relates to acetylene-generators, but more particularly to the carbid- .feeding apparatus therefor; and its objects are to enable carbid of any size to be fed, to prevent the carbid in the hopper from clogging, and to enable the carbid to be fed evenly.

Further objects of the invention will hereinafter appear; and to these ends the invention consists of an acetylene-generator embodying carbid-feeding apparatus for carrying out the above objects, having the features of construction, combination. of elements, and arrangement of parts which have the general mode of. 0 eration substantially as hereinafter fully dgscribed and claimed in this specification and shown in the accompanying drawings, in which Figure 1 is a vertical longitudinal sectional t 1on. Fig. 2 is a vertical transverse sectional view of the apparatus.

Referring to the drawings, A represents the generator-tank, and B is the carbid-hopper, provided with a suitable cover O and supported by the feed-box D, which in turn is carried by the neck E, supported on the tank Preferably between the feed-box and the neck there is a joint F.

The gas generated is led to any suitable. gasometer through the gas-educting pipe H. Any suitable generator may be used in connection with my improved feeding apparatus; but I have simply shown a suitable tank by way of illustration.

The carbid-feeding means is designed to feed any size of carbid evenly and without clogging. -As shown, the carbid is fed by means of an endless traveling jointed conveyer, which in this instance is embodied in an ordinary linked chain .9, preferably, as shown, a round-linked chain scoop-shaped, which travels in a trough t, which is preferably arranged immediately beneath the bottom of the carbid-hopper B and is removably view. of the apparatus embodying the inven secured in the hopper, so that said trough and chain may be removed when desired. Suitable means are provided for guiding and actuating the cham s, and in this instance sald chain is guided by the grooved rolls u, as shown, and is actuated by the star-wheel '0, which may have forked teeth 71;. A space .1 is left between one of the rolls u and the feedbox to permit the carbid to drop into the generator-tank. Beneath the trough t and the chain is preferably provided a protecting inclosing casing y, which preferably extends down into the water, as shown, and'is open at the top and bottom. The object of this protective casing 1 is to prevent the rush of moist gas having access to the chain and actuating devices, so that the ating and guiding parts will not become clogged with lime.

he gas is educted from that portion of the chamber outside of the protective casing y and at a point remote from-the feeding-space chain and its actux. I The protective casing y may be suitably supported beneath the chain upon the lugs z or 1n any other suitable manner, and the guiding-rolls u may be supported in any suitable manner, as by means of the pivotbearings l.

The feeding-chain may be actuated in any suitable manner, althou h th not to be understood as imited to any particular mode of operation and actuation. If desired, the chain may be controlled in any suitable manner by means of the gas generated. It will be seen that the chain 8 is not drawn tight across the guide-rollers u, but is of sufficient length to provide a slack loop, and the chain is driven from the under side in the direction of the arrow that is, from the taut toward the slack side. The object of the provision of slack in the chain is to prevent binding, if pieces of carbid should work their way between the chain and the bottom of the trough 25, thus raising the upper side of the chain and tending to tighten it. By driving the chain from the under side in the direction indicated it will be seen that there loose side.

Obviously some features of this invention I may be used without others and the invention may be embodied in widely-varying forms.

Therefore, without limiting the invention e invention is is always slack on the vIOO , to the constructions shown and described nor enumerating equivalents, I claim, and desire to secure by Letters Patent, the following:

1. In a generator, the combination with the hopper and generatontank, of a removable scoop-shaped trough having downwardly-converging walls and arranged immediately beneath the lower end of the hopper and an endless chain comprising a series of narrow links traveling in the converging .bottom of said trough for feeding the carbld therefrom, there being a feeding-space be tween one end of the chain and the side of the tank.

2. In a generator the combination with the hopper, o a generator-tank, a removable scoophaped trough arranged immediately beneath the lower end of the hopper, an endless traveling round-linked chain for feeding the carbid, there being a feeding-space between one end of the chain and the side of the tank.

3. In a generator, the combination with a hopper, of a trough having inwardly-converging sides and arranged immediately under the lower end of the hopper whereby the carbid is confined substantially within the hopper, a generator-tank, an endless linked chain comprising a series of narrow links moving in said converging trough for feeding the carbid therefrom, there being afeedingspace between one end of the chain and the side of the tank.

4. In a generator, the combination with a hopper, of an endless traveling chain for feeding carbid therefrom, guiding-rolls at either end of the chain, a driving-wheel arranged between said rolls for driving the chain. from the taut toward the slack side, said chain having constant slack-at its under side between the driving-wheel and one of the rolls.

5. In a generator the combination. with the hopper and generator-tank, of an endless traveling chain for feeding carbid therefrom, said chain being so arranged as to provide constant slack on the uno er side, guidingrolls for the chain and a driving-wheel arranged between said rolls for driving the chain from the taut toward the slack side.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.

LOUIS E. SHAW.
